BACKGROUND OF THE INVENTION

The present invention relates to a support device of a bearing angle foran architectural stone, and more particularly, to a support device of abearing angle for an architectural stone that includes a supporterhaving a screw hole formed at the center thereof and being movable alonga spiral thread of an anchor bolt fixed to a wall body, and a cuttingblade part being formed on the supporter and penetrating into aninsulator by a rotational force generated by movement of the supporterso as to be supported in contact with the wall body, whereby the supportdevice can fix the bearing angle, which will be joined later, in astable state without any twist or inclination to thereby obtain a firmsupporting force as being supported in contact with the wall body bybeing inserted into the insulator while cutting the insulator in theform of a circle by the cutting blade part of the supporter, and wherebythe support device can maximize the insulating effect of the insulatorby minimizing a damage of the insulator when the bearing angle isattached to the wall body because the insulator cut by the cutting bladepart of the supporter does not fall out of the supporter but is locatedinside the supporter.

FIGS. 1 and 2 illustrate a bearing angle according to a prior art.

The bearing angle according to the prior art includes: a vertical plate1 being in contact with the surface of an insulator 6 attached to a wallbody 7 in order to fix a stone 8, such as marble, to the surface of thewall body 7 of a building; a vertically elongated hole 2 which is fit toan anchor bolt 5 fixed to the wall body 7, the anchor bolt 7 being fixedby a nut 4; and a horizontal plate 3 on which the stone 8 is put.

According to the prior art, after the insulator 6 is attached to thesurface of the wall body 7, the vertically elongated hole 2 of thebearing angle is fit onto the anchor bolt 5 exposed to the surface ofthe insulator 6, so that the vertical plate 1 is in contact with theinsulator 6, and then, the nut 4 is fastened to the anchor bolt 5inserted into the vertically elongated hole 2, whereby the bearing angleis fixed to the wall body 7.

However, while the nut 4 is fastened to the anchor bolt 5, the bearingangle is not firmly fixed but is fixed in a state where it is twisted orinclined due to elasticity of the insulator 6.

Because the bearing angle is fixed to the wall body in the state whereit is twisted or inclined, in the next step, the stone 8 is not fixed tothe horizontal plate 3 in good order.

Moreover, because the bearing angle does not keep a firmly fixed state,the stone is attached in an instable state, and hence, there is aproblem in that the stone 8 may come away from the wall body 7.

In order to solve the above problems, recently, the insulator 6 that thebearing angle comes in contact is formed in a rectangular shape to getin direct contact with the wall body 7 and has a through hole, and then,the vertical plate 1 of the bearing angle is inserted into the throughhole of the insulator, so that the bearing angle is directly fixed tothe wall body in a state where it gets in contact with the wall body 7.

However, because several tens or several hundreds of the bearing anglesare attached to one building, in order to attach several tens or severalhundreds of the bearing angles to one building, several tens or severalhundreds of through holes must be formed in the insulator, and hence, itis very inefficient.

Particularly, in the case that several tens or several hundreds ofthrough holes are formed in the insulator as described above, theinsulating effect is reduced so much, and hence, such a technique has aproblem in that it is inconvenient and complex because it needsadditional insulating action.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made to solve theabove-mentioned problems occurring in the prior arts, and it is anobject of the present invention to provide a support device of a bearingangle for an architectural stone that can fix the bearing angle, whichwill be joined later, in a stable state without any twist or inclinationto thereby obtain a firm supporting force as being supported in contactwith the wall body by being inserted into the insulator while cuttingthe insulator in the form of a circle by the cutting blade part of thesupporter, and that can maximize the insulating effect of the insulatorby minimizing a damage of the insulator when the bearing angle isattached to the wall body because the insulator cut by the cutting bladepart of the supporter does not fall out of the supporter but is locatedinside the supporter.

To accomplish the above object, according to the present invention,there is provided a support device of a bearing angle for anarchitectural stone including: a supporter having a screw hole formed atthe center thereof and being movable along a spiral thread of an anchorbolt fixed to a wall body; and a cutting blade part being formed on thesupporter and penetrating into an insulator by a rotational forcegenerated by movement of the supporter so as to be supported in contactwith the wall body.

As described above, the support device of the bearing angle for thearchitectural stone according to the present invention can fix thebearing angle, which will be joined later, in a stable state without anytwist or inclination to thereby obtain a firm supporting force as beingsupported in contact with the wall body by being inserted into theinsulator while cutting the insulator in the form of a circle by thecutting blade part of the supporter.

Moreover, the support device according to the present invention canmaximize the insulating effect of the insulator by minimizing a damageof the insulator when the bearing angle is attached to the wall bodybecause the insulator cut by the cutting blade part of the supporterdoes not fall out of the supporter but is located inside the supporter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereinafter, reference will be now made in detail to the preferredembodiments of the present invention with reference to the attacheddrawings.

A support device according to the present invention includes: asupporter 101 having a screw hole 104 formed at the center thereof andbeing movable along a spiral thread of an anchor bolt 12 fixed on a wallbody 14 of a building in order to enhance an insulating effect by firmlyfixing a bearing angle 11, which supports a stone 16, on the wall body14 of the building and minimizing a damage of an insulator 15 when thebearing angle 11 is attached to the wall body 14; and a cutting bladepart 102 formed on the supporter 101, the cutting blade part 102penetrating into the insulator 15 by a rotational force generated byrotation of the supporter 101 and being supported in contact with thewall body 14.

Moreover, the supporter 101 has a flange 105 formed on the outercircumferential surface of the supporter 101 in order to preventdeterioration in the insulating effect by circulating air between thecutting blade part 203 and the insulator 15.

Furthermore, the supporter 101 further includes a dented portion 103formed on the outer circumferential surface of the screw hole 104thereof in such a fashion that a tool 17 is inserted into the dentedportion 103 to screw-couple the supporter 101 to the anchor bolt 12.

Hereinafter, the operation of the present invention will be described asfollows.

FIG. 3 is a perspective view showing a structure of a support deviceaccording to the present invention. The supporter 101 of the presentinvention is first screw-coupled to the anchor bolt 12 exposed to thesurface of the insulator 15 attached to the wall body 14.

After that, a vertically elongated hole formed in a vertical plate ofthe bearing angle 11 is fit onto the anchor bolt 12, and a nut 13 isfastened to the anchor bolt 12, then the coupling is completed.

That is, FIGS. 4 and 5 are views showing an assembling process of thesupport device according to the present invention. The screw hole 104formed at the center of the supporter 101 of the present invention isscrew-coupled to the anchor bolt 12 exposed to the insulator 15 of thewall body 14.

In this instance, after the screw hole 104 is screw-coupled to theanchor bolt 12, while the supporter 101 moves and rotates along thespiral thread, the cutting blade part 102 formed on the supporter 101cuts the insulator 15 in the form of a circle.

Furthermore, the cutting blade part 102 penetrates the insulator 15 bythe continued rotation and comes in contact with the wall body 14, andin this instance, the supporter 101 does not rotate anymore and stopsthe rotation by the wall body 7.

As described above, the supporter 101 of the present invention does notdrop the cut insulator 15 to the outside and holds it in the insidespace of the supporter 101.

Because the cut insulator 15 fills the inside space of the supporter101, the insulating effect is not deteriorated.

Additionally, the supporter 101 may be coupled to the anchor bolt 12 bya user who rotates the supporter 101 manually, but it is too hard tocouple the supporter 101 to the anchor bolt 12 manually because thereare too many supporters 101.

Accordingly, in order to insert an electronic tool 17 into the supporter101, the supporter 101 has the dented portion 103 formed on the outercircumferential surface of the screw hole 104.

In other words, the supporter 101 is automatically rotated by theelectronic tool 17 inserted into the dented portion 103, so that theassembling work of the supporter 101 can be carried out more rapidly.

As described above, when the assembling work of the supporter 101 iscompleted, the existing bearing angle 11 is joined to the anchor bolt12, which is exposed to the screw hole 104 of the supporter 101 firmlysupported. For this, the vertically elongated hole formed in thevertical plate of the bearing angle 11 is fit onto the anchor bolt 12,and then, the nut 13 is fastened to the anchor bolt 12.

In this instance, as shown in FIG. 6, the bearing angle 11 can beregulated in its position before being fastened because the bearingangle 11 is vertically movable inside the vertically elongated hole.

Moreover, after the bearing angle 11 is firmly fixed to the supporter101, as shown in FIG. 7, the stone 16 is put and fixed on the bearingangle 11.

In the meantime, the flange 105 formed on the outer circumferentialsurface of the supporter 101 serves to prevent deterioration ininsulating effect by circulating air through a gap, which is formedbetween the cutting blade part 102 and the insulator 15 by cutting ofthe cutting blade part 102.
